PR build/11881: LIBTHREAD_DB_SO can be undefined.

This patch:

 http://sourceware.org/ml/gdb-patches/2009-04/msg00115.html

Changed behaviour by only defining LIBTHREAD_DB_SO if thread_db.h exists. The
definition of LIBTHREAD_DB_SO and LIBTHREAD_DB_SEARCH_PATH should be moved
outside of #ifdef HAVE_THREAD_DB_H.

This is based on a patch attached to the PR, however, it needed a
tweak, as it was it broke the HAVE_THREAD_DB_H path.

	(LIBTHREAD_DB_SEARCH_PATH): Move outside of #ifdef
	HAVE_THREAD_DB_H.
Move fallback thread_db.h to a separate file.

Having this on a separate file makes it easier to import a new version
-- one can just copy over instead of having to care about preserving
the GDB-specific bits.

We used to have a workaround for this, but the patch to import
gnulib's stdint.h removed it:

  http://www.sourceware.org/ml/gdb-patches/2008-06/msg00050.html

and defs.h made to always include stdint.h.  However, gdbserver
doesn't include stdint.h in its equivalent server.h.

Rather than working around the issue, I've imported a more recent
version from glibc, which itself includes <stdint.h>.  Other than
copyright years and FSF snail mail address, the file hasn't been
touched since 2003 in glibc.  AFAICS, our version was updated last in
2000-09-03.

A note on the apparent license change: before the previous patch, this
file's contents were part of gdb_thread_db.h, and we can see that its
license's text was changed in this patch
<http://sourceware.org/ml/gdb-patches/2009-03/msg00251.html>.  That
was certainly just an easy to overlook grep/sed mistake that fell
through the cracks.

Fix previous entry.
copyright.py: Don't update glibc_thread_db.h.

As glibc_thread_db.h is a 3rd party imported file, we should not
update its copyright year range in the new year process.

The previous patches are still not sufficient to build gdbserver with
our copy of thread_db.h.

First, linux-low.h is including <thread_db.h> directly instead of our
gdb_thread_db.h, although thread-db.c includes the latter.  Then the
'th' field of struct lwp_info is only defined if HAVE_THREAD_DB_H is
defined, which is not true if we're using our replacement copy of
thread_db.h.  We have a USE_THREAD_DB symbol defined if we're building
thread-db.c that's ideal for this, however, it's currently only
defined when compiling linux-low.c (through a Makefile rule).  The
patch makes it defined when compiling any file.
